Andy Mo, Linear Technology Design Note 515 Introduction An increasing number of applications occupy the 30 MHz to 300 MHz very high frequency (VHF) band. Television and radio broadcasting, navigation controls and amateur radios are a few examples. ...
Guy Hoover, Linear Technology Design Note 541 The op amps used to drive 18-bit analog-to-digital converters (ADCs) typically draw as much supply current as the ADC itself, often with a maximum offset spec that is well above that of the ADC. If ...
Richard Cook, Linear Technology LT Journal of Analog Innovation Multicell high capacity batteries are increasingly becoming commonplace in handheld devices and industrial instruments that receive their power from a variety of sources. To maximize ...
Introduction Pulse width modulation (PWM) is a common technique for generating analog voltages from a digital device such as a microcontroller or FPGA. Most microcontrollers have dedicated PWM generation peripherals built in, and it only takes a ...
Tyler Hutchison and Clarence Mayott, Linear Technology Design Note 1031 Introduction High speed ADCs use a sample and hold input structure comprising a fast CMOS switch and a sampling capacitor. When the CMOS switch closes, the sampling capacitor ...
Jian Li and Gina Le, Linear Technology Design Note 524 Digital Power System Management: Set, Monitor, Change, and Log Power Managing power and implementing flexibility in a high rail count circuit board can be challenging, requiring hands-on ...
Marty Merchant, Linear Technology Design Note 507 Introduction Dual-polarity supplies are commonly needed to operate electronics such as op amps, drivers, or sensors, but there is rarely a dual-polarity supply available at the point of load. The ...
David Burgoon, Linear Technology LT Journal of Analog Innovation There are several ways to produce a negative voltage from a positive voltage source, including using a transformer or two inductors and/or multiple switches. However, none are as easy ...
Mike Rose EDN Using the fast dynamic load described in this Design Idea to test the transient response of a power system can reveal many critical operating characteristics. The voltage deviation resulting from a fast current step can provide ...
Tom Gross, Linear Technology Design Note 511 Introduction The LTC3626 synchronous buck regulator with current and temperature monitoring is the first of Linear’s SWITCHER+™ line of monolithic regulators. It is a high efficiency, ...
